Dear Wietse, thank you for your answer.

(There should be warnings logged that saywhich table lookup failed. Does your system perhaps log error and non-error messages to different files? That is not a good idea - it complicates trouble shooting.)
I'm logging with syslog, mail facility. Debug level has it's own file, but it's empty. I cited from mail.info which contains log level info and higher.
I added -v in master.cf, perhaps i'll get a closer hint.
- Next the Postfix SMTP daemon is supposed to find out if the domain exists in DNS, but there are no table lookups involved here.
If postfix has no access to DNS, would that not be a configuration error? The host in question has both an DNS and a reverse DNS entry, and they match.
My bet is that the above error goes away when you delete smtpd_sender_restrictions. The error may then happen at a different point in time, while processing smtpd_recipient_restrictions.
But that's for debugging only? reject_unknown_sender_domain is there for reasons :-)
BTW you need to request a new Zen API key and delete the old one.
Thank you for the hint, i'll do immediately. Kind regards, QNo _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
